'HOISTING MACHINE.

Application filed .enuery 31, 1920. Serial No. 355,458.

To aU 107mm t may concern.'

Be it linoivn that l, CL-Ynn lli-iii, a citizen of the United States,and zi resident of Bartlesville` in the eountyof `Washington and State 5of Oklahoma, have invented certain ner,7 and useful improvements inlloisting Machines, of which the following is a. speeication.

My invention relates to improvements in hoisting machines, it being morepart'culai'- l ly a machinefor hoisting` or pulling the easing, tubingand rods from oil and gas Wells, and it Censis s in the constructions,

combinations and arrangements herein described and claimed.

The foremost object of my inventioiiis to provide combined hoistingmachine and coupling, both being embodied in en automobile trucl; orsinnlir vehicle, ind so arranged that when the coupling is joined'in oneYWay, the ruoli may be operated such, and when the coupling` is shiftinginto connection with the hoisting spperatus, the machine may be used forthe purposes above speciiied.

l @ther objects and advs will appear in the following specification,reference being had to the accompanying drawings, in Which Figure l is sside elevation of the iinll proved machine, showing the coupling joinedwith the v-.fell tube hoisting apparatus,

Figure 2 is a side elevation of the hoisting drum and cooperatingmechanism,

Figure 3 is a longitudinal section of the hoisting drum,

Figure at is an eiid elevation thereof,

Figure is a cross section taken substantially on the line 5 5 of Figure8,

Figure is a detail perspective View of the friction clutch head of thehoistingdrum,

.Figure 7 is :i detail perspective view of t ie shifting lever,

Figures 8 and 9 are detail perspective views of the respectivecooperating coupling members, and

Figure lO is a detail sectional view show-- ing` hoiv the cooperatingcoupling members arel fastened together,

ln carrying out my invention l provide a hoisting drum l, Which ismounted either upon the truck chassis 2, upon the frame of any ordino-rytractor, or in fact, any vehicle Which includes an engine by means ofwhich the drum l may be operated. Briefly deshaft 4l is in connectionwith the plete 9 of the driven shaft l0, then the truck 2 is driven assuc-h, that is to say, it is used an ordinary automobile truck, thehoisting drum l then being out of operation. yljut When thecoupling-.plates are unloosened, by removing the securing bolt ll, inFigure l0', and the coupling plate (3 fastened to the plate 9gv of theshaft l0, then the hoisting drum is rcversed for operation to hoist oilor gas Well casings, tubings and rods, or in feet,ziny other obj ectivhieh it be desired to hois' There is e. universal joint l2 in thesheft l0 between the coupling plate 9 and the diilerential gear ease 13,on the exposed shaft lei, of which there is i sprocket to which thedrive shaft l@ is applied. rllhis chain is also applied to the largesprocket l? nearest the observer in F injure l, Which isv carried by thedrum shaft i8, rlhe sprocket and chain mechanism just described, isduplicated ou the other end of the drum shaft 19 as indicated in Figure3 by the provision of the large sprocket i7 at the left end of theshat't.

l ollers or other suitable bearings i9, support the hoisting drum l onthe shaft 1S, it beingv observed that the shaft itself is journalled inbearings 2O and that the hoisting drum l is normally loose on the shaft.lt is not until the clutch head 2l is vforced inwardly by n eans of thelever 22, that the hoisting drum l. is made to rotate With the shaftlfl, The clutch heed 2l at one end and a collar 23, fixed on the shaftet the other end, hold the hoisting drum in the proper position on theshaft.

The clutch hea-d 2l carries paper-surfaced shoes 24 of'suitablemateriel, for engaging the correspondingly surfaced recess of the drumas clearly shown in Figure These shoes are resiliently held in place byineens ot' the spring in Figures 5 and 6. Connections 26 cause theclutch head to move lill with the splined shifting collar 2T on theshaft 18 when the lever 22 is shifted as eX- plained above.

Various positions of the hoisting drum are held by means of brakemechanism including the drums 28 on the ends of the hoisting drum l, thebrake bands 29 and the lever 30 which has proper connection 3l to bothbrake bands.

The operation may be reviewed to advantage. As stated above, thecoupling plate 6 of the drive shaft 4- is ordinarily joined .and securedto the corresponding plate 9 of the driven shaft l0, thereby causing theoperation of the truck 2 as such. When this arrangement is effected, thetruck may be driven about in the ordinary manner, the hoisting mechanismon top, such times being inoperative.

When it is desired to use the apparatus for the purpose of hoisting, thebolts 1l is unloosened and the coupling plates 6 and SFL securedtogether. By properly manipulating the levers 22 and 30, the hoistingdrum 1 can be operated as desired. Of course at this time the truck 2 ispractically a fixture, the truck being heavy enough to constitute anample foundation for the operations of the hoisting drum.

lt is to be clearly borne inmind that it is through the ability to shiftthe coupling of the drive shaft linto either of the two positionsdescribed, that it is possible to have the use of the automobile truckas such in one instance, and the use of an efficient hoisting mechanismin the other instance.

v`While the construction land arrangement of the improved hoistingmachine and coupling mechanism is kthat of a generally preferred form,obviously modifications and changes can be made Without departing fromthe spirit of the invention or the scope of the claims.

I claim 1. A vehicle including a driven shaft with a coupling plate, andhoisting` mechanism With drive gearing including a coupling plate; and aswingably mounted enginedriven shaft with a corresponding couplingplate, interchangeably connectible With either aforesaid coupling`plate, to operate either the vehicle or the hoisting mechanism.

2.y A vehicle `with a driven shaft having a coupling plate provided witha dove-tail recess, and a hoisting mechanism with drive gearingVincluding a shaft with a coupling plate having a dove-tail recess, anda swingably mounted engine-driven shaft, with a companion coupling platehaving a dovetail Wedge insertible into the recess of either couplingplate, with means for securing it, to drive either the vehicle oractuate the hoisting mechanism.

3. The combination, of an engine-driven shaft With a universal joint,and coupling plate having a dove-tail Wedge; ar vehiclecarried drivenshaft with a couplingplate having a dove-tail recess; and a hoistingmechanism drive shaft, With a universal joint and coupling plate With adove-tail recess, the drive shaft coupling plate being secured to eitherof the latter coupling platos by .fitting the Wedge and'recessestogether.

4C. A vehicle including a driven shaft with a coupling member, andhoisting mechanism with drive gearing including a coupling member; and aswingably mounted engine driven shaft with a corresponding couplingmember, yinterchan'geably connectible With either aforesaid couplingmember, to operate either the vehicle lor the hoisting mechanism.
